Ammonia & pH Detection of the 21st Century

 
  
       
 


Research & Development

The visual approach for measuring ammonia in air and water was derived by Pacific Technologies, a sensor development company, capitalizing on over ten years of ammonia sensor R&D. The method is adapted from technology developed for highly-sensitivity instruments to measure ammonia in biological, medical and food industry applications.

 

Ammonia Aqua Sensing

The achievement has been plastic films responding with easily visible color changes at the ammonia concentrations important in fresh and saltwater systems and can be immersed long-term. Kept in water, the sensors enable the ammonia to be readily determined at any time. The measurement is simply made by matching the sensor color against a reference chart. The sensor film was specially designed to detect NH3 at extremely low concentrations, thereby offering the best protection of the most sensitive aqua systems.

 

Ammonia Gaseous (Air) Sensing

Currently our Ammonia Gas Sensors are predominantly used in the controlled atmosphere storage industries. Apple storage is one such application. However, we are rapidly expanding into other venues such as fish and meat packaging where ammonia can indicate food spoilage. Medical applications have also been identified, particularly in the renal dialysis sector. For further information please contact us.

 

O2 Oxygen Sensing

Our R&D department has also developed several prototypes for detecting oxygen levels in a noninvasive manner. Applications in the wine industry along with the food packaging industry continue to be explored. Modified atmosphere packaging, or (MAP) is at the forefront of this new technology and is increasingly used around the world. For further information please contact us.

 

Bacterial Sensing

Another acheivement we are extremely proud of is the development of proprietary opto-electronic instruments and assay systems for the rapid detection of: E. coli, total coliform, and other harmful microbial contaminants. The Coliform Analyzer is a bioassay system for automatically testing, rapidly identifying, and reporting metabolic-activity of cells/microbes/organisms in fluid samples and deriving information about the number of cells present, their growth and health status. The portable (15 lbs.) testing instrument, that detects the presence of E. coli, total coliform, and other contaminant indicator organisms in 8 hours or less, is the result of over 10 years of research and development funded by the United States Department of Defense.
